Have you seen a Little Free Library? American Profile (which comes in the Denver Post) recently did a great article[1] about them. Little free libraries are popping up all over the country. People build and decorate little boxes and then stock them with books. You can take a book, return it whenever you want, or replace it with a different book. And they're all different designs, too. Check the article for more pictures, or do a Google image search[2]. I saw one in Denver the other day I was so excited that I had to take this picture!
